For decades there have been reports of geometric structures on the floor of Rock Lake in Wisconsin. And after decades of discussion, we still have a lot of fuzzy photos and disregard by most archaeologists.
Nearby, however, is the Aztalan State Park with remnants of mounds built by a Mississippian mound builder culture. Extensive earthworks were built. Did they build something in the lake when it was low? Why would they? Divers claim they found remains of stone pyramids — stone not being a prime material of mound builders. An Aztec outpost?
This is one of those tantalizing mysteries some people keep talking about, yet no convincing proof seems to come forward.
If there were claims of pryamids in any lake nearby me, I would like to know one way or the other if it were true.
